YOS9/YDR057W Summary Help

Standard Name YOS9 1
Systematic Name YDR057W
Feature Type ORF, Verified
Description ER quality-control lectin; integral subunit of the HRD ligase; participates in efficient ER retention of misfolded proteins by recognizing them and delivering them to Hrd1p; binds to glycans with terminal alpha-1,6 linked mannose on misfolded N-glycosylated proteins and participates in targeting proteins to ERAD; member of the OS-9 protein family (2, 3, 4, 5, 6, 7, 8)
Name Description Yeast OS-9 homolog 1
